Product Term Allocator
The product term allocator assigns product terms from a cluster to either logic or control applications as required
by the design being implemented. Product terms that are used as logic are steered into a 5-input OR gate associ-
ated with the cluster. Product terms that used for control are steered either to the macrocell or I/O cell associated
with the cluster. Table 3 shows the available functions for each of the five product terms in the cluster. The OR gate
output connects to the associated I/O cell, providing a fast path for narrow combinatorial functions, and to the logic
allocator.

Cluster Allocator
The cluster allocator allows clusters to be steered to neighboring macrocells, thus allowing the creation of functions
with more product terms. Table 4 shows which clusters can be steered to which macrocells. Used in this manner,
the cluster allocator can be used to form functions of up to 20 product terms. Additionally, the cluster allocator
accepts inputs from the wide steering logic. Using these inputs, functions up to 80 product terms can be created.

Wide Steering Logic
The wide steering logic allows the output of the cluster allocator n to be connected to the input of the cluster alloca-
tor n +4. Thus, cluster chains can be formed with up to 80 product terms, supporting wide product term functions
and allowing performance to be increased through a single GLB implementation. Table 5 shows the product term
chains.
